Today I am at my office wishing I'd brought my PRIV. Germany and Chile playing in a great game. Unfortunately I cannot cast to my screen because the SlimPort adapter hanging to the HDMI inverted splitter is not supported by the KEYone, and only at home I have my Miracast adapters.
Has anyone tried with MHL? A micro-hdmi to usb-c adapter?
The K1 does not support wired video output in any format. That would have been a TCL decision, as nothing about Android or USB-C prevents it, and other devices support it.
I'm sure they have metrics that show it's a rarely used feature and didn't want to spend more time and money to make it happen.
My wife uses a chromecast dongle to stream YouTube to the big LED TV in the living room. Well last night while sitting in my Gaze-Bo I got a notification that her chromecast was streaming YouTube and I was able to change her queue and start playing my stuff on the TV inside from outside! She had no idea what was going on! LOL
